MACHINE r03: MAKIne IIoT-rREssED NUT-BLANKs' To all whom it may concernBe it known that we, WILLIAM S. BIDLE and JOSEPH A. COSTELLO, citizensof the United States of America, residing at Cleveland, in the county ofCuyahoga, State of Ohio. have invented 'a certain new and usefulImprovement in Machines for Making Hot-Pressed Nut-Blanks; and we dohereby declare the following to be a full, clear, and

exact description of the'invention, such as will enable others skilledin the art to which it pertains to'make and use the same.

This invention relates to improvements in machines for makinghot-pressed nutblanks, and pertains more especially to a machine forpressing a piece of hot metal into a nut-blank which has the externalshape and dimensions of a finished nut having a crown-face at one end.

One object of this invention is to effect the reduction to a minimum ofthe amount of metal required in the production of nutblanks.

Another object is to produce a hot-pressed nut-blank which not only hasthe external shape and dimensions of a finished nut having a crown-faceat one end, but is provided with a cavity which is circular in end viewand arranged at and centrally of said I crown-face and extends axiallyof the blank from said crown-face and is adapted to permit the receptionthereby at said crown-face of a tool subsequently employed in elongatingsaid cavity.

Another object is to make said blank uniform circumferentially of saidcavity.

Another object is not only to effect the pressing of a piece of hotmetal into a blank having the external shape and dimensions of afinished nut, but to form the aforesaid cavity during and by saidpressing, to have the aforesaid crown-face of the blank comprise anannular shoulder forming the central portion of said crown-face andarranged concentrically relative to the axis of the blank andsurrounding the aforesaid cavity,to have said cavity concentric relativeto said shoulder, and to have said shoulder uniform in widthcircumferentially of said cavity, so that subsequent elongation of saidcavity to the extent required toform a hole extending endwise of andthrough the blank and any tapping of or necessary operation on the blankto complete the formation of a finished nut shall not disturb theconcentricity'of the cavity at said crown-face relative to said shouldernor disturb the, uniformity Specification of Letters Patent.

Vviththese objects in view, andtothe end. of attainingany otheradvantage hereinafter appearing, this invention consists in certainfeatures of construction, and 1 com.-

bina'tions and relative arrangement of parts,

hereinafter described, pointed out in the claims, and illustrated in theaccompanying drawings. I I In said drawings, Figure l'is a top plan of amachine embodying our invention.

Fig. 2 is a vertical section on line .2.2, Fig. 1. Fig. 8 is a left-handside elevation relative to Fig. 2. Fig. 4:=is a verticalsectiononlin'e44, Fig. 2, looking in the direction indicatedv by the arrow, butthe hot bar. or stock L'is omitted in Fig. 4 to avoid interference withthe. illustration of the die B. Fig. 5 is a section on line 5-5, Fig.2', looking in the direction indicated by the arrow. Fig. 6is a verticalsection taken centrally and longitudinally of the tubularmetal-receiving die of'the machine and illustrates the parts whereby apiece of hot metal is pressed. into a nut-blank having the externalshape and dimensions of a finished nut and provided at one end withacrownface. and a cavity centrally of said face.

14 is a right-hand end view relative to Fig Figs. 6 to 11, inclusive,are drawn full size.

Referring to the drawings, Aindicates the bed of our improved machine,and B represents a stationary tubular die which is shown arrangedsubstantially horizontally (see Figs. 2 and-"6) and adapted to receiveahot metal piece which is to be pressed into a nut-blankhaving theexternal shape and dimensions of a finished nut and provided with acrown-face at one end and a cavity centrally of said ,crownrface. Saiddie is contoured internally in cross-section to conform (see Figs. 6 and12) to the external contour of a finished nut in cross-section. Said dieis rendered stationary in any approved manner, and means for securing adie to the bed A are too well known in the art to require descriptionand illustration in this specification.

A. horizontally arranged endwise movable plunger C extends the maximumdistance into the die B from the forward end or face of thedie, as shownin Fig. 7, or is spaced the maximum distance from said die, as shown inFig. 2, according as the plunger is in the one or the other of itsextreme positions. Said plunger is of course contoured externally incross-section (see Fig. 11) to conform to the internal contour of thedie B in cross-section. Said plunger is carried by and suitably securedto a correspondingly arranged slide E which (see Figs. 1 and 2) isarranged forward of and movable toward and from the die B and engages acorrespondingly arranged slideway a formed in the bed A. The slide E isactuated in any approved manner, being .shown operatively connected by apitinan or link 6 with the crank f of a suitably supported shaft F whichis arranged horizontally and at a right angle to the travel of the saidslide.

As already indicated, the plunger C is adapted to feed a piece of hotmetal into the die B from the face of the die, and a horizontallyarranged endwise movable blankejector G extends in any position thereofinto the die from the rear end of the die.

Said ejector is movable endwise of the die B and in its extreme rearwardposition, shown in Figs. 2, 6 and 7, is spaced far enough from theforward end of the die to permit the hot metal piece which is to beoperated on within the die to be inserted into the die by the plunger Cand to permit said plunger to enter the die during the movement of saidpiece of hot metal rearwardly within the die. The ejector G has itsforward end or face contoured as required to form a crown-face on theadjacent end of the blank to be formed within the die B and is of coursecontoured externally in cross-section (see Fig. 12) to conform to theinternal contour of the die in crosssection. Said ejector extends theminimum distance into the die 13 in the extreme rearward position of theejector.

The ejector G extends into and is suitably secured to and consequentlycarried by a correspondingly arranged slide H which (see Figs. 1, 2 and5) is located rearward of and movable toward and from the die B andengages a correspondingly arranged sl d vay a er-m in h b d A- The s ideH is actuated in any approved manner, having a downwardly projectingmember h which is shown provided (see Figs. 2 and 5) with a lateral slot16 engaged by a block 17 which is movable somewhat up and down said slotand shown pivoted, as at 18, to the upper end of a lever I. Said leveris fulcrumed at its lower end, as at 20, to any suitable support andoperatively connected by a rod J with the upwardly projecting arm 22 ofa rock-shaft K which is parallel with and arranged below the shaft F.The arm 22 is provided at its upper end with a roller 23 engaging thecircumferential or working surface of a cam 24: with which the shaft Fis operatively provided, as shown in Figs. 2 and The shaft K is alsoprovided with an arm 25 which projects upwardly and in the direction ofthe Islideway a and is provided at its upper end with a roller 26 whichengages the circumferential or working surface of a cam 27 with whichthe shaft F is op-eratively provided, as shown in Figs. 2 and 3.

The hot bar or stock L from which is to be punched the hot metal pieceto be fed into the die B (see Figs. 1 and 2) is shown arrangedhorizontally and at a right angle to the path of the plunger C andadapted to rest (see Fig. l) on a seat-forming member 28 with which thebed A is provided at one side of said path. The bed A is shown providedat the opposite side of said path with a stop-forming member 30 arrangedto limit the forward movement of the stock L when the stock has been fedforwardly the distance required to bring its forward end-por tion intoline with said bore preparatory to punching a piece fromthe stock by theplunger during the forward or feeding movement of the plunger. Themanner of feeding the stock, means for supporting said stock, and meansfor arresting the forwardly endwise movement of the stock are too wellknown in the art to require further description. Suffice it to statethat the stock from which the piece of hot metal is to be punched by theplunger is fed in advance of said plunger preparatory to the forwardmovement of the plunger, and that during said movement said piece issevered from the stock and introduced into the die. Figs. 1 and 2 showthe stock fed in front of the die and in advance of the plungerpreparatory to the forward or feeding movement of the plunger.

A stationary metal core M is arranged centrally and longitudinally ofthe rear portion of the die B and centrally of the ejector G. Said coreis parallel with said die and extends forwardly from the face of theejector G in the extreme rearward position of the ejector. Said core iscircular in end view and has its forward end tapering, as at 32, (seeFigs. 6, 7 and 8) toward its forward eXtremity,-'-that is, toward theforward end of the die B. Said core is small enough transversely topermit'movement of the ejector endwise of the'cor'e. is formed on. theforward end of a metal rod m whichiis arranged Within and longitudinallyof the ejector'jG and extendsloosely through the ejector and looselythrough the slide H. Said'core is therefore integral with said rod. :Therod m also extends (see Fig. 2) through a cross-bar P which is arrangedhorizontally and ata right angle to the travel of the slide H andsuitably secured to the bed A. Said crossbar is therefore stationary andarranged to form a stop for limiting the rearward move: ment of theslide H which is shown provided (see Fig. 1) with two rearwardly facingshoulders 33 and 38'arranged at opposite sides respectively of the rodmand abutting against the forward side, of said cross-bar in the extremerearward position of the slide. 7 The rod 712, is screw-threaded from 'apoint'a suitable distance forward of the cross-bar P to a point asuitable distance rearward of said cross-bar. A nut- Q, (see Figs. '1and 2) is screwed into the rod m at the rear side of said crossbarand'abuts against said side of the cross-bar. A nut T I (see Figs. 1, 2,9 and '10) is screwed onto the rod m at the forward side of saidcrossbarand has a circular rear'end-portion t and a rearwardly facing shoulder84: formed at the forward end of said circular portion. Said circularportion of the nut T (see Fig. 10) engages a diametrical enlargement 36of the forward end of the rod-receivingjhole 35 formed in the cross-bar,and the shoulder 34; of said nut abuts against the forward side of thecrossbar. Toaccommodatethe application of the nut T said nut is dividedor split centrally and longitudinally, as at 37, Fig. 9, into halves.Opposite halves of the split nut T areappliedforward of the crossbar Pto opposite portions of the rod min the application of said nut,whereupon the halves or sections thus placed in position relative tosaid rod are manipulated to bring the circular rear end-portion t of thenut into the enlargement 36 of the rod-re ceiving hole"35 in thecross-bar P and to bring the shoulder 34 of said nutinto engagement withthe forward side of the crossbar. It will be observed that propermanipulation of the nuts and T renders the rod m free to be adjustedendwise, and said rod is secured in the desired adjustment by tighteningsaidnuts against the cross-bar P. It will be observed therefore that therod on is held stationary during the operation of the machine throughthe medium of the cross-bar P and the nuts Q, and T. y The endwiseadjustability of the'rod m renders the core M adjustable endwise andconsequently renders said core capable of being adjusted Said corerelative to the die Ban' d ejector G When removed from the rod andthereby render a the; rod removable endwise in a rearward directon-whereupon a new core can be i formed on the forward end of the rodand then the rod replaced. 1 By the construction hereinbefore describedit will be observed that the rodm, and consequently the core M, arestationary but ad-v justable endwise; that the ejector G is opera;

tively connected bymechanism comprising the slide H, theoperative"connection between said slide and the lever I, and'the rod J, with thearm 2250f therock-shaft K; that the arm 22 of saidTOck-Shaf-t isarranged to be ac'tuated-by'the cam 24 of the shaft F to effect theforward or" blank-ejecting movement 'o'ftheflblank-ejector, and thatthe'a'rni 25 of said rock-shaft is arranged to be actu ated by thecam27-jof the shaft F to effect the 'rearwardmovement of theblank-ejector; It will be observed'therefore that our improvedmachinecomprises means whereby the rock-shaft is rocked in oppositedirecjtion's'alternately during the rotation of the shaft Fcontinuously'in one and the same direction and that the ejector isactuated endwise in the one direction or the other according as said.rock shaft is rocked. in g are so relatively arr'anged and timed the eector 1s in ts extreme rearward .posithe one or the other dir'ectiomandthe parts tion upon the feeding of a hot metal pieceinto the die B bytheplunger (land the ejector moves forwardly during the mood ingmovement of the plunger.

' Fig.6 shows the plunger as having fed a'hot metal piece Z, which hasbeen punched by said plunger from the bar or stock L, into the die Bpreparatory to the; contact by said hot metal piece with the core M, andthe relative arrangement of the'parts and the dimensions of said hotmetal piece are such that during the operation of-the machine said pieceis "pressed against and around the core to completely fill the spacearound said core from 'end'to end of the core in the extreme rearwardposition of the ejector. Of coursethe die 13, the forward end of theejector in the extreme rearward position of the ejector, the core M andthe, i;

plunger Gcooper'ate in pressing said hot piece of metal fed by theplunger into a nutblank having the external shape and-dimensionsofa'finished nut and a crown-face one end.

I The rod receiving hole 9 in the ejector (see Figs. 6 and 12) isenlarged diametri cally' at the forward end -"offthe ejector anduniformly all round the. core M so as to form:

an annular recess '38 in said end and internally of the ejector, whichrecess extends around the rear end of said core in the extreme rearwardposition of the ejector and is concentric relative to the core. Saidcore is provided at its rear end and externally with a forwardly andlaterally facing beveled or sloping annular shoulder 40, and thesurrounding Wall of the recess 38 is arranged opposite said shoulder inthe extreme rearward position of the ejector. It will be observedtherefore that the core M is diametrically smaller than but arrangedcentrally relative to the adjacent portion of the rod m on which saidcore is formed, and that the feature of having said rod diametricallylarger rearwardly of the core materially strengthens the core. Said coreis substantially uniform in thickness between its shoulder and thetapering forward portion 32 of the core. The relative arrangement of theparts is such that the hot meta-l piece fed rear-'wardly within the dieby the plunger during the forward movement of the plunger is pressed,(being of course of requisite dimensions) into the shape required tocause the pressed body of metal to fill the space formed between theplunger and the ejector and around the core and to fill the recess 38formed in the forward end of the ejector, so that the hot metal pieceoperated on during the forward or feeding movement of the plunger has,upon the termination of said movement, been pressed into the externalshape and dimensions of the desired blank. In other words, said core isarranged to form an abutment for the hot metal piece fed into the die bythe plunger during the forward or feeding movement of the plunger beforethe plunger has completed said movement, and the core, the ejector, thedie and the plunger are relatively arranged as required to effect theformation, upon the completion of said movement of the plunger of aclosed chamber which has the dimensions of the nut blank to be made andoccupied by the nutblank formed during said movement of the plunger.

The nut-blank 42 made by our improved machine is shown in Figs. 7, 13and 14. As shown in Figs. 13 and 14 said blank is provided at one endwith a crown-face 4L3 which comprises an annular shoulder a l formingthe central portion of said crown-face and arranged concentricallyrelative to the axis of the blank. Said blank is also provided with acavity which is circular in end view and arranged at and centrally ofthe crown-face 48 and surrounded by the shoulder l4. The shoulder 44 isadapted to form thecentral portion of the crown-face of a finished nutmade from our improved nutblank and an abutment, for a check-nut orlock-nut, and it will be observed that the cavity a5 is arrangedconcentrically relative to said shoulder and extends from saidcrown-face formed on one end of the blank axially of the blank in thedirection of but is spaced from the opposite end of the blank. Theshoulder 4:4. is substantially uniform in width circumferentially of thecavity 45 which flares at its mouth, as at 4:6, in the direction of thecrown-face of the blank to facilitate the entrance into the blank of apunching tool (not shown) subsequently employed in the elongation of thecavity. As said cavity extends into the blank from the crown-face of theblank and is formed concentrically relative to the shoulder 4% so as topermit the introduction into the cavity at said crown-face of the toolemployed in elongating the cavity, the concentricity of the cavity atsaid crown-face relative to said shoulder and the uniformity in width ofsaid shoulder circumferentially of the cavity are not disturbed orinterfered with during the elongation of the cavity or during thetapping of the blank to form a finished nut. It is obvious that the coreM forms the cavity 45; that the metal displaced into the recess 38 inthe forward end of the ejector forms the shoulder 44:; that the shoulder40 on the rear end of the core forms the flaring mouth 46 of the cavity45, that the forwardly tapering or conical forward end of the corefacilitates an equal distribution of the metal circumferentially of thecore during the pressing of the piece of hot meta-l into the externalshape and dimensions of the blank, and that by our improved machine iseifected the reduction to a minimum of the amount of metal required informing the desired blank.

Of course the mechanism, hereinbefore described for operating theplunger and the mechanism hereinbefore described for operating theblank-ejector are so relatively arranged and timed that the ejector ismoved forwardly to eject the blank from the die during the recedingmovement of the plunger upon the formation of the blank; that theplunger recedes far enough during the blank-ejecting movement of theejector to permit the blank to be freely ejected from the die by theejector, and that the ejector shall have mo ed forwa dly to or beyondthe forward end of the die and ejected the blank from the die upon thelastmentioned movement of the plunger.
